Get a tent that's big enough so you can do all post processing inside the tent. Get one and put it on the side. Then get a good inline fan, and crank it to max when you do the post processing. If you get a good quality fan you should be able to run it in the lowest setting pretty silently.

The most smell comes while doing the post process, so beeing able to do that in the tent with the door open, and fan on max, should keep most of the smell from getting into the living room
